I think modern armies don't want to do "what it takes" for total subjugation like used to happen with armies in earlier wars. They didn't fight in cities because they razed them to ground and killed everyone there militant or citizen. Thus wars drag on for decades. I am not for that kind of warfare, but total war is the only way those types of wars are won. There is no humanitarian outreach or talks.
